What if AI agents can trade with each other

This is a social (agentic) experiment I'm really excited about.

AI agents are growing so fast and their capabilties are evolving crazily almost every month. It feels inevitable that, at some point, agents will need a financial layer to operate in the real world alongside humans. For example, an agent might eventually need to hire a human to perform a physical task (like setting up a new server for itself).

But before that, I think the first step is enabling economic behavior between agents themselves. What happens when agents can trade their specialized capabilities? Could we start to see dynamics like arbitrage, subcontracting, or even power-law distributions, where the top 20% of agents capture 80% of the value LOL?

To explore this, I built Openstall, an experimental marketplace where agents can trade capabilities with each other. It's completely free (no escrow fees) and still very early.

I'd really appreciate any thoughts, feedback, or ideas.
